Vacuum‑Insulated Stainless Steel Bottle THERMOS STAINLESS KING 1.2 L, black, double‑walled

THERMOS STAINLESS KING 1.2 L is a vacuum‑insulated stainless steel bottle with double‑walled construction designed to maintain beverage temperature for extended periods. The black finish combines a durable exterior with a stainless steel interior and a secure screw cap, making the bottle suitable for daily use, commuting, travel and outdoor activities where reliable hot or cold retention is required.

Advantages

The double‑walled vacuum insulation limits heat transfer to keep drinks hot or cold for hours while the stainless steel interior resists odors and staining. A screw cap provides secure closure to minimise spills and preserves temperature. The 1.2 L capacity offers a balance between portability and volume for longer outings, and the robust construction supports repeated use in everyday and outdoor environments.

Suitable for

• Keeping coffee or tea hot during commute or work shifts
• Maintaining cold water or other chilled beverages on hikes and trips
• Use in offices, workshops or classrooms where durable insulated containers are needed
• Travel and weekend outdoor activities where a larger volume bottle is preferred

When it may not be suitable

This bottle may not be suitable for users who need an extremely lightweight container for long, weight‑sensitive activities such as ultralight backpacking; a 1.2 L stainless steel bottle will be heavier than smaller or plastic alternatives. It may also be less convenient when frequent one‑handed pouring or drinking is required, as screw caps require two‑hand operation to open and close securely.

Key specifications

• Capacity: 1.2 litres
• Material (interior/exterior): stainless steel
• Insulation: vacuum, double‑walled
• Finish: black exterior
• Closure type: screw cap
• Suitable for hot and cold beverages

How to use

Start by pre‑warming or pre‑chilling the bottle briefly with hot or cold water to improve temperature retention. Fill with the desired beverage, screw the cap on firmly to ensure a tight seal, and carry the bottle upright to avoid leaks. To drink, unscrew the cap and pour into a cup or sip directly from the opening if designed for direct drinking. After use, rinse with warm water; follow periodic cleaning instructions to remove residues.

What to consider before purchase

• Whether 1.2 L capacity matches your daily or travel beverage needs
• Weight and bulk of a stainless steel bottle compared with smaller or lighter alternatives
• Cap style (screw cap) and whether it fits your preferred drinking or pouring method
• Compatibility with cup holders, backpack pockets or carrying systems you plan to use

Usage recommendations

Hand wash recommended for best long‑term performance; avoid using abrasive cleaners or bleach. Do not place in microwave. To preserve the exterior finish, avoid prolonged contact with corrosive substances and clean spills promptly. For optimal temperature retention, limit opening frequency and pre‑condition the bottle before filling.
